Answer:

#GCF(12,30)=6#

Explanation:

First, split each number into their factors.

#30=1,2,3,5,6,10,15,30#
#12=1,2,3,4,6,12#

Now we look for the greatest number appearing in both.

Both numbers have these factors:
#1,2,3,6#

The greatest common factor will be the largest number in this list, which is #6#.
